SanDisk SDSDQAS4-064G 64 GB microSDXC 100 MB/s Read 20 MB/s Write

64 GB microSDXC for continuous video

This SanDisk microSDXC card offers 64 GB of capacity and is built for 24/7 recording in security cameras and dash cameras. It delivers sequential read speeds up to 100 MB/s and write speeds up to 20 MB/s. The card carries a Class 10 and UHS-I U1 rating for sustained capture. It targets OEMs and integrators who need elevated endurance for long-term deployment.

Simple slot insertion with device checks

Installation requires inserting the card into a compatible microSDXC slot until it clicks. The main issue arises when the host device only supports microSDHC, which cannot address 64 GB capacities. Users should also verify that the device sustains the required write throughput for continuous recording. No drivers or software configuration are needed for basic operation.

Verify microSDXC support and endurance needs

Before ordering, confirm the camera or recorder explicitly supports microSDXC cards up to at least 64 GB. Check whether the device can utilise card health monitoring features for early warnings. Ensure the application demands the elevated endurance rated for constant overwriting. The product line scales to 1.5 TB if larger capacity is required later.
